When sugar crystals are crushed, tiny electrical fields are created, separating positive and negative charges that create sparks while trying to reunite. Wint-O-Green Life Savers work especially well for creating such sparks, because wintergreen oil (methyl salicylate) is fluorescent and converts ultraviolet light into blue light. [17] [18]
The reduced iron compounds cause poorly drained soil to appear gray or blue, and because reduced iron is soluble in water, it may be removed from the soil during prolonged saturation. This often exposes the light gray colors of bare silicate minerals, and soils with a low chroma from iron reduction or depletion are said to be gleyed .
Saccharum officinarum is a large, strong-growing species of grass in the sugarcane genus. Its stout stalks are rich in sucrose, a disaccharide sugar which accumulates in the stalk internodes. It originated in New Guinea, [1] and is now cultivated in tropical and subtropical countries worldwide for the production of sugar, ethanol and other ...
The Zea mays lineage split off from this grass about six to seven thousand years ago. Phytolith analyses from Bolivia suggest that several varieties of maize were present in the Lake Titicaca region of Bolivia almost 1000 years before the Tiwanaku expansion, when it was previously thought to have been introduced in the region.
Andropogon virginicus is a perennial grass forming narrow clumps of stems up to just over a meter in maximum height (around 3 feet 3 inches). Its stems and leaves are green when new, turning purplish to orange and then straw-colored with age. It produces large amounts of seeds small enough to disperse on the wind. This grass is successful in a ...
The name copperas dates from times when the copper(II) sulfate was known as blue copperas, and perhaps in analogy, iron(II) and zinc sulfate were known respectively as green and white copperas. [18] It is on the World Health Organization's List of Essential Medicines. [19]
On the other hand, a badly scratched container will result in many lines of small crystals. To achieve a moderate number of medium-sized crystals, a container which has a few scratches works best. Likewise, adding small previously made crystals, or seed crystals, to a crystal growing project will provide nucleating sites to the solution.
Luzula campestris, commonly known as field wood-rush or Good Friday grass is a flowering plant in the rush family Juncaceae. [1] It is also one of the plants known as chimney sweeps [2] or sweep's broom [3] because of the brush-like appearance of their flowers. [4] This is a very common plant throughout temperate Europe extending to the Caucasus.
